The PRPNet MEGA project is being moved to BOINC sometime after the current work on PRPNet completes.

It's a PPS project, similar to PPS and PPSE, and as such will share the PPS statistics and badges. It will search exclusively in the area just above 1 million digits, making it an ideal place for people to find mega primes.

MEGA PRPNet port is empty :D When might we see it activated on BOINC?

p.s. First load of units run-time extrapolates to 50-55 minutes on my 3770K. Initial boinc "estimate" was about 2:16:00. No worries.

On some CPUs, the workunits have more than one FFT size. On my Haswell i5 3670K, some are 200K and some are 256K. I've seen run times of about 50 minutes and 66 minutes.

Other CPUs will see different FFT sizes. The server (pre-AVX Intel), for example, uses 256K for all of the workunits (no 200K).

Got a few of these for a brief break from ESP charge to amethyst. Only got a few so far but they're all resends already - why? Are people breaking them already?

Is there a badge for Mega or goes all into PPS?

Hello,

what CPU is better for crunshing PPS-Mega (LLR)

i can get cheap a workstartion with xeon E5 2670 Sandy Bridge 8 Core.

or is better a selfasselmbled new rig with

Skylake Xeon E3-1275 v5 or 6700K ?

Thanks

General requirements for MEGA is as long as you can provide at least 2MB/core cache, then you simply want the most combined core clock speed possible. If you go below 2MB/core cache, you hit a performance wall in ram speeds.

Based on my recent testing of processor scaling, assuming each of these processors is run at base clock with no overclocking or turbo, the i7-6700k would be the fastest, the E3 at 90% relative overall throughput, and E5 76% relative. If you stretch to the 5820k, that would be 109%.

If you overclock, it becomes a 2 horse race between the two i7 processors.

As a long term consideration, the FFT size wont stay at 256k forever. When it requires the next size up, the ideal cache per core will increase also. Here the i7-5820k would have an advantage at 2.5MB/core. The E5 would also similarly benefit. They wont get faster, but the 2MB/core CPUs will get slower at that point.

As a final consideration, do you need one fast system, or would multiple cheaper systems also be a possibility? It will have to be worked out on value but two 4MB cache i3-6xxx series systems could be interesting.

Can you afford the cheapest 5820k + x99 + 4x4 gb of DDR4? The price should be pretty similar to a 6700k setup, depending on where you live.... if so, it's going to trounce the 6700k with it's 2 extra cores and twice the RAM bandwidth.

How many tests are needed in the original Proth Prime Search before it gets to the range covered by Mega Proth Prime Search?

Has there been any recent challenges for Proth Prime Search (excluding Mega and Extended versions)? As far as I can tell there hasn't been a PPS only challenge in three years.

4. PPSE is not available for challenges. (PPSE is what's pushing SGS off the T5K list, and we do not want to exacerbate that process.)

There's been a moratorium on PPS and PPSE challenges as we wished to delay SGS being pushed off the bottom of the T5K list for as long as possible.

I Interpret this to mean "we would prefer to push other projects T5K entries off the list, but not our own." Is that correct?

A search for primes containing 2^1290000 gives 283 hits spanning position 4718 to 5000. So, any prime entering T5000 above that will be knocking off SGS.

No it is not.

What's with all the antagonism? What's your point? You started by asking, effectively, "Can we please have a PPS challenge?", to which the answer was "Yes.", and you followed up by trying, twice, to pick a fight. I'm at a loss to understand why. Is there something we're doing that you would prefer we not do? Is there something we're not doing that you would like us to do?

I will never understand what is so special about primes. Everyone today, can make sieve, can make search in any range, and report any prime that is found. Currently there is 275 primes missed above SGS , to remove SGS from TOP 5000. So what: people can always take PPSE, will find prime in similar speed that will find SGS prime today.
Or you can use NEWPGEN and make own sieve file with only few digits above in exponent: for example 1290005. Any prime found will be bigger then SGS:and will push all SGS primes.

SGS primes was long enough on Top 5000: let they make place for new ones.

I'm sorry for being antagonistic. This is mainly due to a very negative interaction I had with one of your admin's when I was maintaining ProthSearch. I got the distinct impression that PrimeGrid (either the admins or the community) was all about PrimeGrid and "to hell with everyone else". I think you can understand why I interpreted your sentence as I did, even though you were not the admin I had difficulty with.

As for a PPS challenge, I think that one is long overdue. I also think that PrimeGrid should consider combining some projects, specifically ones that are very closely linked. A PPS challenge would go a long way to merging PPS and PPS Mega. IMO, Cullen and Woodall could be combined.

Like I said, I don't have the exact numbers, but I think we're a long, long ways from PPS getting to a million digits. Let me see if I can dredge up some rough numbers...

Okay, assuming the density remains constant, there's about 130,000 candidates for every 10,000 increase in 'n'. 'N' is currently about 2,460,000, and needs to go to about 3,320,000 to catch up to PPS-MEGA. That's an increase in n of 860,000, which should be about 11,180,000 candidates. Including double checking, that's 22,360,000 tasks. In the last 24 hours 7646 PPS tasks were completed. 22360000/7646 equals 2924 days, or almost exactly 8 years.

Wow. That is a lot of tests. I wonder how many more would be done per day if a week long challenge were issued.

A really good challenge runs at about 10x normal. It would need to be a really, really, long challenge. Even if we wanted to do something silly like run an 10 month challenge, there's technical reasons why we couldn't do it. And human factors as well. Not many people would be interested in such a long challenge.

Maybe the subset of work for the challenge could focus on a specific set of k to get them to 3,260,000 rather than extending all k within the challenge.
